unable to save/load mmm models after upgrading to 0.11.1

[johnherr]

After upgrading to the newer version of pymc_marketing, my existing pipelines broke. After when loading a saved model I get KeyError: "['y'] not found in axis"

I replicated this error in the mmm_case study.ipynb notebook by running the following after the model is trained:

mmm.save("test.nc")
b = MMM.load("test.nc")

In the output I see the following:
--> [563] model.build_from_idata(idata) [565] if model.id != idata.attrs["id"]: [566]msg = ( [567] "The model id in the InferenceData does not match the model id. " [568] "There was no error loading the inference data, but the model may " [569] "be different. " [570] "Investigate if the model structure or configuration has changed."

Hi. Can you raise an issue for this, it will be easier to track.

Can you provide which pymc marketing version used to saved off the model
